Description
Ground connection for the synchronous rectifier.
Ground Pin. The control circuitry of the IC and lower power driver are referenced to this
pin. Return separately from other ground traces to the (-) terminal of C OUT .
Feedback Voltage and Short Circuit Detection pin. The inverting input of the Error
Amplifier and serves as the output voltage feedback point for the Buck Converter. The
output voltage is sensed and can be adjusted through an external resistor divider.
Whenever V FB drops 0.25V below the positive reference, a short circuit fault is detected
and the IC enters hiccup mode.
Output of the Error Amplifier. Internally connected to the inverting input of the PWM
comparator. An optimal filter combination is chosen and connected to this pin and
either ground or V FB to stabilize the voltage mode loop.
UVLO input for V IN voltage. Connect a resistor divider between V IN and UV IN to set
minimum operating voltage.
Soft Start. Connect an external capacitor between SS and GND to set the soft start rate
based on the 10μA source current. The SS pin is held low via a 1mA (min.) current
during all fault conditions.
Input connection to the high-side N-channel MOSFET. Place a decoupling capacitor
between this pin and P GND .
Connect an inductor between this pin and V OUT .
No Connect.
High-side driver supply pin. Connect BST to the external boost diode and capacitor as
shown in the Typical Application Circuit on page one. High-side driver is connected
between BST and SWN pin.
Input for external 5V bias supply
